Why didn't Thrall just off Gallywix?

Alright so Thrall, who hates slavery, and just fought this Trade Prince... who'd pretty much implied he was going to enslave him alongside the player, spares Gallywix... why?

No one better? - Sassy's right there, management experience and all.

Gallywix is 'a typical goblin'? Uh so what? Thrall's bashed in heads before, I'm not saying Gallywix isn't a capable leader for the goblins, but leaving the vast majority of the people to be slaves or drown in a sinking ship isn't exactly good for business either, it ups the chances he'll end up like his predecessor after all, doesn't it?

I'm just not following Blizzard's reasoning with his storyline, him being allowed to live or remain in power just doesn't seem reasonable to me.

Yeah I can't see Gallywix staying as the goblin leader forever. He does not care about his people even. He was prepared to sell and sacrifice them as slaves. He only joined the Horde so that he would be rescued from the lost isle and be safe. He's in for the cash, to exploit, and chances to try out new experiments and gadgets. I hope he ends up as a boss in Orgrimmar.

"I bring light where there is darkness. Hope where there is despair. Judgement where there is injustice. I AM PALADIN!"

I also think a lot of Goblins have debts toward Gallywix so that may also make him the "right" leader for them, at least during that time period.

1. Mercy is for people who deserve it though, and Thrall's bashed heads open before, take Burx from Cycle of Hatre and such for example. Thrall's killed tons of people. Mercy is for people like Sergeant who only wanted to defend themselves and Thrall let him go because he wasn't an insane megalomaniacal asshat.

2. Again, Sassy.

3. Not... -really- they were slaves. And then un-slaves after he beat Gallywix which would've been the same result if he'd just killed Gallywix, do remember that most of the player charcters npc allies -helped- fight against Gallywix.

Actually, the reason is ebcause Blizzard made the player the second richest and second most powerful Goblin on the Isle. If someone would have offed Gally it was the player. And Blizz can't have every goblin be the leader of the Goblins so they left Gallywix allive

Maybe Thrall thought it would look bad to kill the race's leader then say "So...you in for joining my faction?" to the rest of the goblins or maybe he looked the other way because he knew that the rest of the goblins would have the freedom to go/do whatever they wanted when they joined the horde
